Abstract
The disclosure provides a backlight module. Light reflected back and forth inside a display device is fully utilized, and luminescent efficiency of a luminescent device inside the display device is improved. In addition, the backlight module has a simple structure, which can solve technical problems of occurrence of strip black lines and uneven brightness that result from an application of a conventional backlight module in a large-scale display device by simply adding a refractive layer or a reflective layer.
